Description/Abstract Sulfate was determined nephelometrically with 2-aminoperimidine sulfate suspensions at pH 2. The method was applicable from 2 to 30 ..mu..g of sulfate in 20 ml of sample, with an estimated relative precision of 10 percent.^Procedures for purification and recovery of the 2-aminoperimidine hydrochloride reagent are given.^After colored organic material was removed by a column of the polymeric adsorbent Amberlite XAD-2, the sulfate content of surface waters was determined with this method.
